Just remember to start your engine first to not drain your auto battery.

We run the engine on the vehicle the device is plugged into and we’ve never had a problem with the performance of the inflator going slow or draining the car battery

It connects via a cigarette lighter adapter and is not as loud as other compressors I've heard (just make sure your engine is running, whilst using the compressor, to avoid draining your battery)

So, the draw for 11 lbs of air killed the battery

It just stops adding air but continues to drain battery unless car is running.

Or you can damager product and/or drain your car battery.

This is very useful in cold weather climates where filling a tire can quickly drain the battery of the car.

What took the longest was positioning my other car next to it because the battery in the Mustang was dead from sitting

I couldn't top off more than 2 tires before it nearly drained the battery

..the bad news was I had a dead battery

Me, I have a hefty 12v11AH gel-cel battery to power it, mounted with compressor on wood, w/

works as it should.

The product works as it says

I suggest reading directions on box as well as on the user guide.

In fact the pump showed my bicycle tire at 67psi at the end of the pump, after I removed the nozzle as fast as I could the pressure was below 50.The fact that it died so quickly and others have commented on that as well, says they need to QC the product.

I purchased this compressor for my recumbent trike tires, as well as for my car

A design suggestion would be to change to a Rapid-T Valve (like found on good bike floor pump) to clip on rather than screw on to attach to the tire
